Characters of Polyethylene Coating Steel Pipe

1, long service life

Polyethylene coating steel pipe highest molecules, has a good stability and aging resistance, work at normal temperature and pressure conditions, the service life can ensure more than 50 years.

2, corrosion resistance,

Molecular structure of polyethylene high stability, resistance to chemical corrosion, such as natural gas, liquefied gas, artificial gas without secondary anti-corrosion equipment. Chemical substances that exist in the soil will not produce any degradation of pipes.

3, good flexibility, polyethylene pipe is - a kind of high toughness of the steel tubes, the elongation at break of more than 500%. Polyethylene pipe flexibility makes it easy to bend. Engineering can be by changing the way for piping around obstructions, on many occasions, of flexible pipe can reduce the dosage of the pipe and reduce the cost of installation.

4, excellent resistance to impact, and ability to resist earthquake

Polyethylene of low temperature brittle temperature is extremely low, can be in 60  ~ 60  temperature range, the safe use of jaasiel uneven settlement has very strong ability to adapt. During the winter construction, because the material good impact resistance, pipe material embrittlement will not occur.

5, good wear resistance

Test showed that the wear resistance of polyethylene pipe is four times that of steel tube, especially in the field of slurry transportation, compared with the welded steel pipe, polyethylene pipe has better wear resistance.

6, small flow resistance of polyethylene pipe has a smooth inner surface, the manning coefficient of 0.009. Smooth inner surface and the adhesive properties of guarantee polyethylene pipe has a traditional pipe higher transmission capacity, but also reduces the water conveyance pipeline pressure loss and energy consumption.

7, good environmental protection performance

Polyethylene pipes not adding stabilizer of heavy metals in the process of machining, material non-toxic harmless, is a kind of green environmental protection material, and recyclable polyethylene material itself, won't produce pollution to the environment.

8, good flame retardant, antistatic performance

I company specialized research and development of flame retardant, antistatic PE pipe material, suitable for in certain places such as inflammable and explosive.

9, safe and reliable connection method

Polyethylene pipes mainly adopts hot-melt or fused connection, essentially keep interface material, structure, and the identity of the pipe body itself, to realize the joint with pipe integration, can effectively resist hoop stress to internal pressure and axial tensile stress, no water and air.

10, qualitative light, easy to carry, simple and convenient construction

Polyethylene pipe proportion was only about 1/8 of the carbon steel pipe, easy to carry, easy bending, welding process is simple rapid, comprehensive project cost is low, has significant economic benefits.
